5G

2.
Introduction
 Mobility is one of the most invigorating features, having
an enormous impact on how communication is evolving
into the future.
 Mobility in 5G networks requires new level of mobility
support as compared to traditional mobility.

3.
0th Generation
 0G refers to pre-cellular mobile telephony technology
in 1970s. These mobile telephones were usually
mounted in cars or trucks, though briefcase models
were also made.
 Since they were the predecessors of the first generation
of cellular telephones, these systems are referred to
as 0G (zero generation) systems.

1
Generation
 First-generation mobile systems used analog
transmission for speech services.
 A voice call gets modulated to a higher frequency of
about 150MHZ and it is transmitted between radio
towers using Frequency-Division Multiple
Access(FDMA).

7.
Disadvantages of 1G
 It has low capacity, unreliable handoff, poor voice
links, and no security at all since voice calls were
played back in radio towers, making these calls
susceptible to unwanted eavesdropping by third
parties.
 Very slow speed 28kbits/s to 56kbits/s.

Advantages over 1G
 Consumes less battery power.
 Improves the voice clarity.
 Reduce noise in the line.
 Secrecy and safety to the data and voice calls.

3
Generation
 2G networks were built mainly for voice data and slow
transmission. Due to rapid change in user expectation
they do not meet today’s wireless needs.
 3G networks provide the ability to transfer voice and
no-voice data over the same network simultaneously.

Generation
 5G technology is going to be a new mobile revolution
in mobile market.
 The next major phase of mobile telecommunication
standards.
 Real wireless world that is a complete WWWW.
